Request codes for memcached

[Bonjourz]

You have mentioneed "Graphene with Eleos RPC: Will be made available shortly" in the README. But I can't get them now... Could you please tell me where the codes is?

I guess the codes is located at https://github.com/acsl-technion/graphene/tree/eleos, am I right?

Thanks!

Indeed. I've updated the README file with the appropriate link.
Also, note that there are under-review PRs at the main Graphene-SGX repo for the RPC code. This can be more useful since the are integrated with a more up-to-date version of Graphene's code.

Hi, In the eleOS paper:

We modify memcached to use SUVM (75 LOC changed), and run it in enclave using the Graphene library OS , enhanced with Eleos’s RPC mechanism for faster system calls.
That means you modified the Graphene-SGX to support exitless RPC and the memcached to support SUVM.

But the repository you have mentioned above(https://github.com/acsl-technion/graphene/tree/eleos), I only see the modification on the Graphene-SGX, and nothing to do with memcached...

Could you please provide the codes of the modified memcached?

Thanks!

The memcached modifications were only tested for the experiments described in the Eleos paper and are likely unstable. Instead of publishing them we offer the option to use SUVM with an automatically instrumented memcached using a Cosmix. See the following link for the memcached sample code: https://github.com/acsl-technion/cosmix/tree/master/samples/memcached

Cosmix is engineered to be robust and is compatible with newer Graphene-SGX versions or other SGX frameworks such as SCONE, Anjuna, etc. In our experience it makes running memcached and other complex applications with SUVM much easier.

I got it!

Thanks for your detailed explanation!
